    Description
    This course is designed to acquaint students with the methods, techniques, and tools of the astronomer. Indoor labs demonstrate classical methods and techniques of science. Students learn the critical thinking processes needed to acquire and analyze scientific data; become familiar with visible objects including constellations, planets, star clusters, galaxies, meteors, and the phases of the moon; and learn to locate objects visually and use astronomical coordinate systems. The development of skills in the operation of optical telescopes is emphasized. This course is designed for students with an interest in learning about night skies and the tools astronomers use to explore the cosmos. Observatory facilities are utilized often, weather permitting.
